Safety Reminder Common safety precautions Carefully read the following safety precautions for a thorough understanding.  Follow the instructions and procedures described in this manual to operate this centrifuge safely.  Carefully read all safety messages in this manual and the safety instructions on the centrifuge.  Safety messages are labeled as indicated below. They are in combination with signal words of “WARNING” and “CAUTION” with the safety alert symbol

to call your attention to items or

operations that could be dangerous to you or other persons using this centrifuge. The definitions of signal words are as follows:

WARNING：Personal Danger Warning notes indicate any condition or practice, which if not strictly observed, could result in personal injury or possible death.

CAUTION：Possible damage to centrifuge Caution notes indicate any condition or practice, which if not strictly observed or remedied, could result in damage or destruction of the centrifuge. NOTE：Notes indicate an area or subject of special merit, emphasizing either the product’s capability or common errors in operation or maintenance.

 Do not operate the centrifuge in any manner not described in this User Manual. When in doubt or have any troubles with this centrifuge, ASK FOR HELP.  The precautions described in this User Manual are carefully developed in an attempt to cover all the possible risks. However, it is also important that you are alert for unexpected incidents. Be careful operating this centrifuge.

WARNING  This centrifuge is not explosion-proof. Never use explosive or flammable samples.  Do not install the centrifuge in or near places where inflammable gases are generated or chemicals are stored. 2

 Do not place dangerous materials within 30cm of the centrifuge.  Prepare all necessary safety measures before using samples that are toxic, radioactive or contaminated with pathogenic micro-organisms. Use of these is at your own responsibility.  If the centrifuge, rotor and accessories that have been contaminated by solutions with toxic, radioactive or pathogenic materials, clean it according to the decontamination procedure as specified.  If you require service at site, please sterilize and decontaminate the centrifuge in advance, and then notify the service center the details of the materials and procedure.  To avoid electrical shocks, insure hands are dry before handling the power cord or turning on/off the power switch.  For safety purposes, do not enter within 30cm around this centrifuge when it is in operation.  While the rotor is rotating, never release the door lock.

 Unauthorized repairs, disassembly, or modifying the centrifuge except by our service center are strictly prohibited.

CAUTION  This centrifuge must be located on a firm and level table.  Make sure the centrifuge is horizontal before running.  Do not move or relocate the centrifuge when it is running.  If fluid spills in the rotor chamber, please promptly clean and dry with a dry cloth to avoid sample contamination.  Ensure to remove any objects and fragments of the tubes dropped inside the rotor chamber before running the centrifuge.  Cautions with rotor (1) Always check for corrosion and damage on the rotor surface before using it. Do not use the rotor if an abnormality is found. (2) Do not set the speed beyond the allowable minimum speed of the rotor kits (rotor and adapters). Make sure to run it below the allowable maximum speed. (3) Do not exceed the allowable imbalance. (4) Use the rotor and tubes within their actual capacities. If any abnormal condition occurs during operation, please stop it immediately and contact our service center. Notify the service center is a warning code if displayed.  Vibrations are likely to damage the centrifuge, contact our service center if abnormality observed.

2.2 Transport and storage conditions （1）Storage temperature: -40℃~55℃. （2）Relative humidity: ≤93%.

3. Installation This section describes the instructions that you should abide when install the centrifuge to ensure your safety and the optimum performance. Before moving the centrifuge, the rotor must be removed.

WARNING  Improper power supply may damage centrifuge.  Make sure the power source conforms to the required power supply before connecting.

3.1 Location （1）Place this centrifuge on a firm、flat and level surface, ensure the four feet of this centrifuge stand on the counter firmly. Avoid installing on a slippery surface or surface prone to vibration. （2）Ideal ambient temperature is 20℃±5℃, avoid placing the centrifuge in direct sunlight if temperature exceeds 30℃. （3）Keep clear of the centrifuge at least 10cm on both sides and at least 30cm behind it to guarantee the cooling efficiency. （4）Keep away from heat or water to avoid sample temperature issues or centrifuge failures.

3.2 Connection of the power cord and grounding WARNING  To avoid electrical shocks, ensure your hands are dry when touching the power cord.  This centrifuge must be grounded properly. An minimum 10A outlet providing a sufficient ground is required, and this must meet local safety requirements.

Time adjusting

Main interface is as figure 6-1. Left knob is setting speed, rotate the knob at the scale you want to set; right knob is setting the time, rotate the time knob at the scale you want to set, then the centrifuge will run. At the same time, the speed lamps will display when the speed arrives at the position.

6. Rotor Preparation 6.1 Prepare the samples 6.2 Inject the samples into tubes

CAUTION 

Do not overload samples into the centrifuge which will cause leaking.



Do not exceed the actual capacity allowed in the user manual.

6.3 Keep the tubes balanced 

Although the centrifuge can accept sample balancing by eye, we recommend that you keep this centrifuge in a well-balanced condition to extend its life expectancy.



Never intentionally run the centrifuge under an unbalanced condition even though the allowable imbalance is not exceeded.

6.4 Inspect the rotor Check the rotor for corrosion or scratches before using. CAUTION 

If any abnormality such as scratches are found, stop using the rotor and contact our service center.



Only manufacturer ’s rotors must be used with the unit.

6.5 Symmetrically load centrifuge tubes into rotor CAUTION 

Make sure the rotor is securely fixed on the shaft. Otherwise, the rotor may be moved off while rotating and cause damage to the centrifuge and rotor.

8. Maintenance 8.1 Cleaning CAUTION 

If do not follow the recommended instructions for cleaning or disinfecting this may damage the centrifuge.

（1）Centrifuge 

If the centrifuge is exposed to ultraviolet rays for a long time, the color of the door may be changed or the label may be peel off. After using, cover the centrifuge with a piece of cloth to protect it from direct exposure.



If the centrifuge needs cleaning, clean it with a cloth or sponge moistened with a neutral detergent solution.



Sterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution.

（2）Rotor chamber

8

CAUTION 

Do not directly pour water, neutral detergent or disinfectant solution into the rotor chamber, otherwise fluids may leak into the drive units and cause corrosion or deterioration to the bearings.



If the rotor needs cleaning, clean with cloth or sponge moistened with a neutral detergent solution. Sterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution.

（3）Drive shaft 

We recommend regular maintenance for drive shaft. You can wipe the drive shaft with soft cloth, and then apply a thin coat of silicon grease.

（4）Door 

Clean and sterilize the door using the same method as the section（1）above.

（5）Rotor 

For sample leaks in the rotor, rinse the rotor with water，and dry it completely.



The rotor should be checked every 3 months to ensure the tube and rotor holes keep are clean.
